We took a bonus test in AP History. I had one question that was too good a joke to pass up (I'd share it, but it's an in-joke to my home town that anyone born in the past 30 years wouldn't get). My teacher nearly fell out of her chair and asked if she could share my answer with the punchline of the joke. I told her she was welcome to if I got the point.
I got one point on that test.
